基于LabVIEW的双燃料发动机测试系统设计与开发

Design and Development of Test System for Dual-Fuel Engines Based on LabVIEW

基于NI数据采集卡及调理模块,配合发动机各关键位置的传感器,采用LabVIEW软件编写采集程序和串口通信程序,开发了双燃料发动机实时监控测试系统。利用标准信号发生器等设备校准所开发的测试系统,并在双燃料发动机试验台上获取了部分测试点的实时状态参数,验证了所设计开发的测试系统的精确度。

Based on the NI data acquisition （DAQ） card and SCXI module togemer with the sensors mounted on the engine, the real-time monitoring and test system was developed for dual-fuel engines through the acquisition programs and serial communication programs designed by LabVIEW. The de-signed test system was calibrated by using the standard signal generator and then its accuracy was verified on the experimental bed by comparing with the real-time parameters of the dual-fuel engine.
